We work in a war zone but we're not unstable

For small startups, keeping clients happy, investors intrigued and turning a profit isn't easy ... on a good day.

Try doing it with key team members gone, sirens blaring and rockets firing at your city.

With the ongoing fight in Gaza, Israeli entrepreneurs in Tel Aviv have been operating under these circumstances for the past two weeks.

Racheli Levkovich -- alumni of the 8200 EISP accelerator and co-founder of Zuznow -- was recently talking to an investor on Skype when a siren went off.

"We literally took the computer with us [and] moved to the stairwell in the middle of the call," recalled Levkovich. "When we talk to companies outside of Israel, we try to hide it. We don't want them to think we're an unstable company and to change their minds [about doing business with us]."

Zuznow, a development platform that automatically converts websites into mobile sites, is alreadyoperating one person short, which issignificant given that there are only eight people.

The employee has been gone for about two weeks now, one of 65,000 IDF reservists called up to serve in the ground offensive in Gaza.

Levkovich said the Israeli market understands any delays, but she's trying to respond to U.S. requests as quickly as before.

Doron Nir, CEO of mobile marketplace HappySale said the environmental and emotional distractions are a reminder to stay focused.

"It [makes] you want to succeed in what you're doing even more," said Nir. "The essence of the Israeli startup community is that, no matter what, we need to be successful."

(But Nir is quick to note that Tel Aviv is getting it "very easy" with only a few bombings a day.)

HappySale has only six employees -- who have not yet been called up to serve. Because their team is so small, each person manages particular functions. If someone like their iOS developer is called to serve in the reserves, the impact on business would be profound.
